I bought this to replace the Shimano BB I was using with my XT cranks. The original had developed a creak after a few weeks. I replaced that one with another Shimano, and the noise returned a few weeks later. The Hope BB doesn't creak after 3 months of abuse. It even "feels" smoother, though I'm probably just imagining that.

Delivery was on time. I have purchased from this vendor many times without any issues. Jenson has great customer service. I was in the Riverside, CA. store recently. Customer service did a great job again. Thanks Jenson.

Seems to spin more freely that a stock xtr bb. I have always just used Shimano bb;s just because there cheap and I can replace them once or twice a year with little expense, the latest versions of Shimano bbs seem to be a little stiff and have some resistance ,that is why I went with the hope, this time.the test of time will prove durability.

I know HOPE makes good products so when I found out the make BB's, why not get a BB. What I like is can use reguler BB tool, no special tools like Chris King. What I don't like are no way to grease internal bearings like my Chris King. Did notice a creaking from BB from day one, will disassemble and re grease. Only time will tell if it last long. If wasn't on sale, probably would have just bought a CK BB. Ride on!

My stock was Shimano Hollowtech BB (68 mm). I bought into the hype of smoother bearings with Hope; I didn't notice any real difference compared to my 5 year old Shimano which is still in use. The only difference is that you can service the Hope cartridge bearings with the appropriate tools (another ($40+) and the Shimano is labeled as non-serviceable, although some blog have indicated this can be attempted. I can't justify the 3 times higher cost of the Hope compared to Shimano. I will stick with Shimano.

BEST ANSWER:Short answer: yes. From what I can see from a quick Google Image search, this model crankset certainly appears to have the standard Shimano Hollowtech 24mm-diameter spindle - and why would they make one lower-end model with it's own, different spindle size... So, again, this BB will work with that crankset. This is assuming that your frame has either a 68 or 73mm-width BB shell, which it most likely does, and you can easily measure without any disassembly of anything. For 73mm, leave out the spacers; for 68mm, use one between the frame and each cup.

Does anyone know which aspect of this bb is ceramic and which is steel ball bearings I was thinking it was ceramic bearings with a steel ring that the bearings sit in if anyone knows more about the bearings and seals I would love to hear about it?
